Grandmother 39513

Jana and Tomáš received a total of 105 CZK from their grandmother. Jana got a third more than Tomáš. How many crowns did everyone receive?

Correct answer:

J =  60
T =  45

Step-by-step explanation:


J+T=105
J = T + T/3

J+T = 105
3J-4T = 0

Pivot: Row 1 ↔ Row 2
3J-4T = 0
J+T = 105

Row 2 - 1/3 · Row 1 → Row 2
3J-4T = 0
2.33T = 105


T = 105/2.33333333 = 45
J = 0+4T/3 = 0+4 · 45/3 = 60

J = 60
T = 45
